The adjusting member 4 is arranged in the adjusting hole 311 to adjust the assembly position of the first hinge bracket 3 in the width direction of the first assembly part 12. By arranging the adjusting member 4 in the adjusting hole 311, the assembly position of the first hinge bracket 3 in the width direction of the first assembly part 12 can be adjusted, which directly affects the position of the door body, thereby realizing the fine adjustment of the gap between the two doors, compensating for the errors to a certain extent, and ensuring the good closing and aesthetic appearance of the door body. It should be noted that the adjusting method is not limited to the double-door, but can also be used for the single-door to adjust the gap between the door and the door frame in the closed state.

[0041] In some embodiments, in order to enable the adjusting member 4 to adjust the assembly position between the first hinge bracket 3 and the first assembly part 12, specifically, the first hinge bracket 3 comprises a first bracket body 31 and a first assembly plate 32, preferably, the first bracket body 31 and the first assembly plate 32 are integrally formed and vertically connected, the first assembly plate 32 is provided with a first waist-shaped hole 321, the length direction of the first waist-shaped hole 321 is consistent with the width direction of the first assembly part 12, a first fastener 322 is arranged in the first waist-shaped hole 321, and the first fastener 322 is connected with the first assembly part 12 through the first waist-shaped hole 321 to realize the assembly effect of the first assembly part 12 and the first hinge bracket 3, and when the first fastener 322 is not tightened, the first assembly plate 32 of the first hinge bracket 3 can be slid on the first assembly part 12 along the length direction of the first waist-shaped hole 321.
